The effects of oxygenated fuels use on the emissions from motor vehicles is assessed using IM240 emissions data collected in the Denver metropolitan area during 1995 and 1996. The results of the 1996 test year are very different from the 1995 results. The benefits of oxygenated fuels on the reduction of CO emissions from the 1995 IM240 data are consistent with the results of ambient data analysis reported previously, but much lower than MOBILE 5A predictions. Due to some disturbing aspects of the study, additional studies of the effects of reformulated gasoline on NOx emissions are necessary.
